Calcium carbonate overdose

Definition

Calcium carbonate is an ingredient that is commonly found in antacids (for heartburn) and some dietary supplements. Calcium carbonate overdose occurs when someone accidentally or intentionally takes more than the normal or recommended amount of a product containing this substance.

This is for information only and not for use in the treatment or management of an actual poison exposure. If you have an exposure, you should call your local emergency number (such as 911) or the National Poison Control Center at 1-800-222-1222.

Symptoms

Home Care

Do NOT make a person throw up unless told to do so by poison control or a health care professional. Seek immediate medical help.

Before Calling Emergency

Determine the following information:

Patient's age, weight, and condition

The name of the product (ingredients and strengths, if known)

When it was swallowed

The amount swallowed

Poison Control

The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national hotline number will let you talk to experts in poisoning. They will give you further instructions.

This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.

What to Expect at the Emergency Room

The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. Blood tests may be done. Symptoms will be treated as appropriate. The patient may receive:

Activated charcoal

Tube through the mouth into the stomach to empty the stomach (gastric lavage)

Outlook (Prognosis)

Because calcium carbonate is considered fairly nontoxic, recovery is quite likely. Chronic overuse is more serious than a single overdose. Few patients die from an antacid overdose.
